Thunderbird 140.9.1esr (64-bit) keeps changing default email account from a MS365 account to my Gmail account on startup
Hello!
I am using Thunderbird 140.9.1esr (64-bit) on a Ubuntu 24.04 system. Every time I restart Thunderbird, it reverts to a little used Gmail account as the default account. I have several accounts, but my main email account is a MS365 account. I reset the setting, but every time it is restarted, the default goes back to Gmail. I have tried everything that I've found online, but cannot correct this behaviour.
Do you have any suggestions or assistance?
Many thanks!

You don't say what you consider to be "the setting", but when you go to <Account Settings>, each account has a "Set as Default" button, and you will then see a star by the designated default account. Is this not what you see?
Hi Lin,
Yes, that is what I see, however, when I set my desired email account as default, it always reverts back to the Gmail account when Thunderbird is restarted.
So, is the little star moving to your desired account, but then when you reopen Thunderbird, it's back to the Gmail account? And the "Make Default" button's grayed-out property reverts as well?
Do you notice any other preferences not sticking? I ask because the Default Account designation is stored in the prefs.js file, located in your Profile. If one preference is not sticking, I would expect to see other properties not sticking, either.
First thing to try is to restart Thunderbird in Troubleshooting Mode. Go to menu item <Help | Troubleshoot Mode...>. Let it temporarily, not permanently, disable all your add-ons. After it restarts, try changing the default account again. If it's successful, that could indicate a misbehaving add-on.
Please let us know the results. If that doesn't do it there are some other things to try.
Hi Lin,
Yes, when I restart Thunderbird, the little star appears beside the Gmail account, and I have to manually go back to my MS365 account and make it default again, which it accepts as long as I don't restart the program. The "Set as Default" box seems to operate normally.
I haven't noticed any other preferences not sticking.
I tried what you suggested in Troubleshoot Mode. Doing so made my three MS365 email accounts disappear, and the Gmail became the default. My two IMAP accounts were unaffected.
Just for clarification, I have: three MS365 email accounts (including the one that I want to have as default); two IMAP accounts; and the one Gmail (also IMAP) account. In order to have the MS365 accounts operate in Thunderbird, I have an add-on called Owl, which was needed to provide MS Exchange Server support.
Curious to know if you have any other suggestions. Many thanks for your assistance to date.
